' To all whom it may concern: l

Be it known that I, FRANZ KYLL, a citizen -of the Empire of Germany,residing at Co- '\logne'onthefRhine, in the Empire of Gr'er-v vrows ofsuperposed balls, Fig. 3 is a horizon.-

many, have invented a new and useful Rectifying-Column, of which .thefollowing is a specification. f

. My invention consists in improvements in rectifying-columns of thekind in which the drip plates are arranged to carry balls on speciallconstructed vertical tubes, .whereby a ve'ry this division of the-downwardly flowing slnglings is obtained.

The chief improvement consists in new drip plates which are capableofsupporting 'the balls and can bea comparative y easily cleaned. Eachdrip plate has ribs of either an undulated or a serrate cross sectionk,which ribs are provided `with su'ciently 1111-' merous and largeopenings lfor the passage of the rising vapors,.while between them holesare disposed for the singiings, their area being reduced by theinsertion of needles or wires. 'The singlings .running down the endentneedles or wires will necessarily be diivided into a drizzlin rain.

n Other improvements W1 Vbe hereinafter explained and pointed out in theclaims.

I will now roceed to describemy inven-4 tion with -re erence to theaccompanying drawings, in which- 'Y Figure 1 is a vertical sectionthrough an improved rectifying-.column without a still, Fi .l2 is a partout of Fig. 1 on an enlarged sce and 'shows one drip plate with two talcross sectlonthrough the rectifying-columnbetween any two of its dripplates, the balls being removed,Fig. 4 is a vertical section' through apart of the rectifying-column in a plane at right an les tothat of Fig.2, Fig. 5 is a part out of ig. 2 on a magnified scale and showsa needleinserted in ahole and supported byits head, Fig. 6 is a vertical sectionin a plane at right angles to that of Fig. 5 and shpws twoneedles, Figs.7 and 8 are similar to Figs. 5 and 6 respectively, the only dierencelbeing that the smgle needles are replaced by needles secured in asupportingrod, Figs.v 9 and k1Q are similar to4 .Figs.'7 and 8 resectively, the rod with the needles being rep aced by a repeatedly bentwire,the Vertical doubled parts of which are inserted in the holes, Fig.11 shows a modified drip plate, and Fig. 12 is avertical central crosssection through the same.

Similar characters of reference refer to similar parts' throughout .theseveral views.

The rectifying-column illustrated at Figs. l1 to 4 consists of a closedbottom section l, several intermediate sections 2, 2, a coveredtop'section 3, and several drip plates 4, 4 between the severalsections, all these parts being bolted together. Each drip plate 4 has'several (here eight) parallel hollow ribs, so that its cross section isundulated, as is shown at Fig. 2. The cavity. of each rib 5 extends froma partition at one end to another partition at the other end of the rib.

1The furrows formed between the ribs are at the ends partly closed bypartitions 6, 6 which extend upward to a certain height as shown at Fig.4. Thus open channels 7, 7 are formed, which are separated from theannular channel 8 along the inside of the section 2 by the saidpartitions 6, 6. In each channel 7 the drip plate 4 is provided with aseries of holes 9, 9, through which needles 10, 10 are introduced. Theseneedles 10, 10 may be provided with heads 11, 11 (Figs. 5 and 6), bywhich they are supported. The heads are shown to have spiral grooves, asthey are assumed to be formed from wire spirally wound around the upperends of the shafts and afterward worked off. However, these spiralrooves are immaterial to m invention. rlghe needles 10, 10 reduce thearea of the holes 9, 9, so that very small passages 33, 33 are left forthe sin lings (Fig. 6). This is to be explained by t e fact, that theupper edge of the hole 9 is not in a horizontal plane, but in the curvedsurface of the furrow, so that the'spherical head of any needle 10 cancome in contact with the edge of the hole 9 only in two opposite points(see Fig. 5) and consequently twol crescentshaped areas will be leftbetween the edge of the hole 9 and the surface of the head. In the'walls of the ribs 5, 5 are large openings 12,12, which extend down tothe height of the partitions 6, 6 or-nearly so and permit the risingvapors to pass through the drip plate 4 upward. Where so preferred, aheating serpentine tube 13-may be secured in'each section 2 at such aheight above the drip plate 4, that its several turns passing betweentheribs 5, 5 remain clear of the surfaces of the latter. Without thesection 2 the serpentine 'tube- 13 is connected with tubes 14, 15, whichin turn by collecting tubes (not shown) are connected with some sourceof heating fluid. Balls 16, 17 are placed on the drip plate 4 ina mannerclearly shown. Packing rings 23, 23 are in sertedl between the flangesof the sections 2, 2 and the end sections 1 and 3, and the several dripplates 4, 4 for tightening the apparatus. The bottom section 1 by itsconnection 18 maybe connected with some source of vapor, or it maybereplaced by the respective chamber of the ordinary still. The topsection 3 is provided with a connection 19, through which the singlingsfrom any known source are admitted to the rectifying-column, while theother connection 20 of the section 3 serves as an outlet for therectified vapors which are'then further treated in any known manner.

During the operation of the rectifyingcolumn the vapors entering itthrough the connection 18 (or direct from the still, as the case may be)pass upward consecutively through the several drip plates 4, 4

until they in their rectified state escape through the connection 20,while the singlings entering the apparatus through the connection 19flow into the annular channel 8 in the uppermost chamber, where they iowover the partitions 6, 6 into the parallel channels 7, 7 whence theyflow through the narrow passages 33, 33 around the needles 10, 10 andalong the latter into the next lower chamber, where they fall on theballs 16, 16, 17. Thus they successively pass downward through the holes9, 9 in the several drip plates 4, 4 and through the connection 21 ofthe bottom section 1 (or direct) into the still, as usual. Should someof the needles 10, 10 get jammed, it will be suiicient to turn on steamfrom some source into the bottom section 1 through a nozzle 22 or thelike; then the steam will push all the needles 10, 10 upward against theser- -pentine tubes 13, 13, in other words move and thereby loosen them.Any dirt, such as grains of sand, or impurities or the like, that mayhappen to be deposited on the inside of the column, will be collected bythe respective annular channel 8 and prevented by the partitions 6, 6from getting into the channels 7, 7 and blocking up the holes 9, 9.

The needles 10, 10 not only reduce the area of the holes 9, 9, but alsofacilitate the down'- ward run of the singlings in thin layers andenable them to fall in a rapid succession in very small vdrops so thatthe singlings go downward in a drizzling rain.

Where so preferred, some heating fluid, for example superheated steam,may be passed through the several serpentine tubes 13, 13 for preventingthe rising vapors from any or premature condensation, which latteraccording to experience takes place during the passage of the vaporsthrough the openings 12, 12 in the' several drip plates 4, 4.

It is an advantage of the new drip plates 4,4, that the turns of theserpentine tubes 13, 13 can be placed between their .hollow ribs 5, 5and thus brought 'r'nto close proximity to the openings 12, 12 forpreventmg any undesired condensation of the vapors.

However the heating serpentine tubes 13,13

may be dis nsed wlth, 1f so desired.

The nee es 10, 10 in every channel 7 may be rigidly vconnectedy with oneanother by means of a horizontal rod 24 (Figs. 7 and 8), to which theyare attached. Of course the rod 24 requires to be so shaped as not tocompletely close the areas in the holes 9, 9 around the needles, seeFig. 7. Or the rod 24 with theneedles 10, 10 may be replaced by a wireso repeatedly bent as to form several doubled vertical parts 25, 25

and several connecting horizontal-parts 26,

26, as is shown at Figs. 9 and 10.

The drip plates may be modified in the manner shown at Figs. 11 and 12,in which case their hollow ribs 27, 27 are made rectangular in crosssection and are provided in their tops with openin 28, 28 and in theirside walls with open1ngs-29, 29. Between the high ribs 27, 27 lowundulated ribs30, 30 with holes 31, 31 in their tops for the `needles10, 10 (or parts 25, 25) are provided on the drip late 32, so that in asimilar manner as be ore any impurity, which may fall on the plate 32,is prevented from blocking up the holes 31, 31.

The total area of the openings 12, 12 in the drip plates 4, 4 or of theopenings 28, 29, 28, 29 in the drip plates 32 is preferably made aslarge as possible so as to facilitate the ascension of the vapors.
